2 Claims.

Our invention relates to a device for regulating the temperature ofwater in preparation for showers, baths, or the like, and the objects ofour invention are:

First, to provide a very simple thermostatically controlled valve meansfor regulating water taken from the hot and cold water supply;

Second, to provide a device of this class in which a thermostat isadjusted to provide a particular thermal heat to the mixed water as itpasses to the outlet from the device:

Third, to provide a device of this class in which the temperatureregulator is very positive and is not easily disturbed or moved out ofits position;

Fourth, to provide a device of this class in which the water isthoroughly mixed together immediately after it passes from the hot waterinlet and cold water inlet into the device so that it is thoroughlymixed when it reaches the thermostat for controlling the valve at theinlet and outlet of the device;

Fifth, to provide a device of this class which is positive in its actionthroughout;

Sixth, to provide a device of this classwhich is very simple andeconomical of construction, efiicient in itsaction and which will notreadily deteriorate or get out of order. I

With these and other objects in view as will 'appear hereinafter, ourinvention consists of certain novel features of construction,combination and arragement of parts and portions as will be hereinafterdescribed indetail and particularly set forth in the appended claims,reference being had to the accompanying drawing and to the characters ofreference thereon which form a part of this application in which:

Figure 1 is a longitudinal sectional view of our device for regulatingwater taken from the line l-l of Fig. 2 showing parts and portions inelevation to facilitate the illustration; Fig. 2 is a sectional viewtaken from the line 2-4 of Fig. 1

plate I, support 8, rocker arm 9, link member I0, thermostat II, rackshaft i2, pinion l3, support 14, shaft 15, stufling box It, index plateII, handle l8, friction spring l9 and water outlet 20 constitute theprincipal parts and portions of our water regulating device.

The water inlet pipes I and 2 are screw-threaded into the base member 5in spaced relation to each other at its lower side, as shown best inFig. 1 of the drawing. This base member 5 is provided with tapered seatportions 5a and 5b in the upper side in intercommunicatin relation withthe inlet pipes l and 2, as shown best in Fig. l of the drawing. Thisbase member 5 is rectangular in shape and secured to one side ,thereofand along the ends -is the main casing member 6 which extends upwardlyand is provided with a curved upper end, as shown best in Fig. 1 of thedrawing. Secured on one side is a plate 50 which is shaped to fitagainst the other side wall of the base member 5 and open side of thecasing member Sand is secured thereto by means of bolts 50 which arescrew-threaded into a flange 617 on the main casing 6, thus providing arectangular in cross section casing member exmember 5 and thus providingtending upward from this base provided with a curved upper end, awater-tight casing.

Secured in the inner part ofthe curved upper end is the outlet pipe 20which communicates V with an opening in the upper end of said casing.

showing parts and portions in elevation to facilitate the illustration;Fig. 3 is a fragmentary side elevational view taken from the line 3-3 ofFig. 2; Fig. 4 is a fragmentary sectional view taken from the line 44 ofFig. 3 and Fig. 5 is a fragmentary sectional view taken from the line 55of Fig. 1 showing parts and portions in elevation to facilitate theillustration.

Similar characters of reference refer to similar parts and portionsthroughout the several views of the drawing:

The cold water inlet pipe I, hot water inlet pipe 2, cold water inletvalve 3, hot water inlet valve 4, base member 5, main casing 6, mixingPositioned in this casing 6 some distance above the base member 5 is amixing plate I which is provided with a plurality of mixing orifices 1cand with valve guide openings 1a and lb which also serve as mixingorifices. Positioned in the opening 111 and 1b are valve rods 31; and larespectively. On the lower end of the valve rod 311 is secured thecone-shaped valve member 3 which is adapted to fit in the valve seat 5a.in the member 5 and secured on the lower end of the valve rod 4a isacone-shaped valve 4 which is adapted to fit in the valve seat 5b in thebase member 5.

These valve rods 30 and 4a are pivotally supported on the extended end\of the rocker arm 9 which is pivoted centrally on a shaft 9a which issecured in the side wall of the casing 5,v a's shown 'best in Fig. 2 ofthe drawing. The valve rods 3a and 4m are connected to the rocker arm 9by means of pivoted members 91) and 90.

Between the shaft 9a and the pivot member is another shaft 9:1 towhichis pivotally connected the link members III at its lower end.

This link member is connected at its upper end to a thermostat memberll. Secured centrally on this thermostat member II at its upper side andextending upwardly is a rack shaft l2 which is provided with gear teethI20, which are adapted to mesh with a pinion 13. mounted on a shaft l5which extends through a stuffing box It secured on the casing member 6aso that upon revolution of the shaft I5, the pin l3 will be revolvedshifting the rack shaft l2 upwardly or downwardly depending upon therevoluble movement of the pinion B. This shaft is supported near itslower end by means of a support I! with a bearing Ila in which the shaftI2 is mounted and at the upper end is provided a bearing 8a in which theupper end of the shaft I2 is mounted which bearing 8a is supported bymeans of a support 8 which is secured to the opposite side of the casing6 near its upper end, as shown best in Fig. 1 of the drawing.

Secured on the outer side of the casing member 6a around the shaft i5 isan index plate I1, as shown best in Figs. 2 and 3 of the drawing. Thisindex plate I! is provided with a plurality of index characters at itsperiphery and is also provided with a plurality of slots IIa extendingfrom its periphery inwardly a short distance adapted to receive the endof the spring member I9 to provide a positive support for the end of thespring member l9 which prevents the shaft from turning when it is notforced around-by the handle l8 which is secured on the end of the shaft.Supported on this handle I8 is an arm member I80 in the extended end ofwhich is a screw 18b which serves, as an adjusting screw to engage thespring 19 for adjusting it in frictional relation 'with the notches IIain the index plate I1.

The operation of our water regulating device is substantially asfollows:

Hot and cold water passes through the hot and cold water pipes I and 2past the valves 3 and 4 and is mixed thoroughly by passing through theorifices 1c and around the valve rods 3a and 4a through the openings Iaand lb and passes out through the outlet pipe 20 at the upper end. Thethermostat H is regulated by turning the handle l8 to certaintemperature positions as indicated by the end of the spring l9 relativeto the notches Ila which are numbered at the periphery of the indexplate ll, as shown best in Fig. 3 of the drawing. If the temperature ofthe water passing through the orifices 10 is not the proper temperaturethe thermostat II will tend be limited to this particular construction,combination and arrangement, but desire to include in the scope of ourinvention the construction, combination and arrangement substantially asset forth in the appended claims.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is:
